Working 12-13hr days. Gym Routine

Hey Everybody.

Just wondering how people with long shifts go about with maintaining a routine?

I work from 5:30am - 6pm, 7 days on 7 days off, sometimes 10 days on 4 days off. Jumping between dayshift and nightshift.

I get up at 2/2:30 everyday and do a PPLRPPL routine.

is anyone else in a similar position? how do u manage fatigue?

Sometimes i feel extremely fatigued i was wondering if maybe working out after work would be better.

thanks guys.
